Mudge Posted February 2, 2003 Share Posted February 2, 2003 Originally posted by JAMIE T:My Zcar will be just like the Mustang. Total control. An extension of myself. My Z28 is a terrible car IMO. I have the exact opposite experience. I had a 97 Cobra that was more difficult to keep straight, than my Camaro. Sits too high, and shorter wheelbase, like trying to drive a pickup truck. I am suspicious of anyone who can't drive a Camaro reliably, if its riced out with a lowering job and bad shocks, and no relocation brackets in the rear to fix the LCA geometry after lowering, or things of that nature, then it is clear why the person can't drive it fast. The stock shocks have a 30k mile lifespan, not great at all. Longer, lower and wider, the Camaro is setup a bit better. You will also find that lap times are almost always lower than in a Mustang, because it takes a good driver to pull the speed out of it, if you visit www.CamaroMustangChallenge.com the road racers there will confirm this. There was however, Don Trask's son who was spanking everyone in his Fox body Stang some couple years ago, well setup and with a good driver they are great cars. In my experience so far with the 240Z, it gives you alot of warning and is a very friendly track car, I love it. Quote Link to comment Share on other sites More sharing options...

I'm aiming for maybe half of what the original poster is looking at. V8 in another 240Z though with a nasty-cam, shooting for 500 HP would be very sweet. Dont know when that will happen.

I am only offering my input, mostly in regards to people who dream beyond thier means. Going from a nearly stock car to quadrupple the horsepower, is not wise IMO.

Guest JAMIE T Posted February 2, 2003 Share Posted February 2, 2003 Mudge, My Z28 still has a completely stock suspension(honestly had no idea the shocks had such a short life expectancy). My wife drives it daily. It has long tube headers that hang low. I think I just never gave it a chance. It's not how it drives fast, just how it drives under normal situations. When you put your foot in it for short spirited bursts, it's fun as hell. I just don't like the way it FEELS, heavy slow responding. I'm not really into it(the Z28). I'd rather see the motor and trans put into a Zcar, than waste my time lugging around a 3500lb car. My 240Z scaled in at 2250lbs. Thats more like it!!! I think my 240Z is a great handling car, I can't wait to give it some HP. Quote Link to comment Share on other sites More sharing options...

Mudge man...build a NA 3.1L I'll send you a good buildsheet that's pretty cheap too...if you do the work yourself most expensive part is prob the crank and all the machining COMBINED and anyway..that NA 3.1L will SPANK on roadrace..table flat power/torque band *edit* oh yeah..you should go with a shaved N42 head over size valve 292 / .490 cam =) road race woo hoo high compression gogogo!

240Z Turbo Posted February 2, 2003 Share Posted February 2, 2003 The funny about this whole post is this....Who on here has driven a 240Z with 500hp on the street? Yet you seem to know what exactly it is going to do and what a fool that person is for driving that car. Let me talk about driving a 240Z on the street with 1000hp. Wait, I have never driven a 240Z on the street with 1000hp! I have driven my car on the street 18psi and the 100shot with the Nitto drags and from a roll it did not even spin the tires, but accelerated like a bat out of hell. The car makes well over 500hp, about 475@wheels with nitrous and no problems. Good tires, decent suspension and LSD and you can have some fun. So what if the tires spin a bit, you can still control it. Quote Link to comment Share on other sites More sharing options...
Pop N Wood Posted February 2, 2003 Share Posted February 2, 2003 No, I am most certainly not a Hillary fan. However, just as there is no reason for an assualt weapon, there is no reason for a 500hp street car. Man, are you on the wrong site. "Need" is a very poor argument. If we followed your line of reasoning we would all be trading in our Z's for bus passes and renting the Honda Insights for the occasional road trip out of town. I am sure Hillary and her friends would argue there is no "need" to ever modify a car from stock. And obviously since they personally can't see a "need", then no one else could possibly have such a "need". Thus it is up to the government to protect people from their own "stupidity" and outlaw it. We are talking past each other here (and having some fun in the process). I think this thread has clearly spelled out the issues with trying to get 500 HP out of a Z engine. But as long as the person doing it goes into it knowing what the challanges are, then there is no point getting judgemental about it. And for your assault weapon remark (once again, Hillary comes to mind), probably best to leave that for a different site altogether. While there are always two sides to everything, I say don't buy into the media ignorance on the topic. I can see a very real "need" for such weapons, and so did the framers of our constitution.

Guest zline Posted February 3, 2003 Share Posted February 3, 2003 hell yeah its cheap... you can find 90% of the parts in a junk yard the only expensive part is prob the crank =) i wonder how much boost the KA24 pistons can handle [Edited for profanity by Drax240z] Quote Link to comment Share on other sites More sharing options...
Bob_H Posted February 3, 2003 Share Posted February 3, 2003 You guys are unreal. [internet sarcasam] yea, that's what I meant[/internet sarcasam]. Geez. Man, are you on the wrong site Its freakin symantics. Want vs need vs desire. Since I broke out the dictionary before, I'll do it again. Need: necessity, obligation,(no, not that kind of obligation). I personally WANT 500 hp. Actually, I'll likely WANT more. (I am putting the RB into my Z Jim) Noone NEEDS that power outside of a track environment. I can't see a single reason why you would ever need 500 hp outside of the track. That is not to say you can't USE it, or ENJOY it. Symantics. Again, not a NEED for more power, but the lack of a NEED for 500 hp in a 2300lb car on the street. There is no reasonable justification for it. However, that is exactly why most of us will build it. Because we can and we want to. And don't drape me with the assault weapons issue or use it to divert the issue. There is a difference between keeping our freedoms, etc.. Personally, I don't give a rats butt what others think about weapons issues. Me personally? Not an issue I even worry about or have a position on. I was discussing your example. I serve and fly daily so all of us have the priveledge to do, buy and own the things we desire. I am willing daily, do give my life if necessary so you and others can continue to do that. I WILL NOT get into this discussion, either about weapons, or what our military is doing now. If you want to discuss that, don't hijack this thread, start a new one, and you won't find me in it. Jim, I realize you may think this is fun,(or funny), but I felt it was pushing the limits there. Enough thread hi-jacking. -Bob Quote Link to comment Share on other sites More sharing options...
jeffp Posted February 7, 2003 Share Posted February 7, 2003 Well most of you dont live in Southern CA LOL. I drive a 500Hp turbo car and I dont have any problems with it. I also do have a boost controller, but I find I drive it turned up most of the time. I also run race fuel most of the time, so it is expensive, but you are ready to go anytime and there aint nothing like blowing away one of these "hotrods" on the street. And also 5.00 for C-16 is cheap, try 7.50 a gallon. True I dont use all of the power most of the time, but getting on the freeway @ 4:30 in the morning is really fun. Now you are thinking how can I afford to drive the car, well one really good thing is that the car still gets 30-32 mpg when I dont have my foot in it. The car is tuned very well, and it is using a 300zx ECU. I have power when I want it and cruise power when I want that also. So stupid, I dont think so, not with a turbo application because you can adjust for the power you want easily, kinda like the INDY cars do, its just that simple if you set the car up right and dont need to floor it every time you take off from the light. I will tell you one thing tho, the looks on the faces of the guys that think they are going to just blow you no problem, and they get their slow car blown away by a little nissan 280zx is priceless. I look for mustangs, vettes, vipers, and just about anything that is fast to have a little fun with, I dont know, maybe I am stupid, but it sure is fun.

Bob_H Posted February 7, 2003 Share Posted February 7, 2003 Hey, that's out of context! You said: So stupid, I dont think so, not with a turbo application because you can adjust for the power you want easily, Then you aren't driving 500hp, but a reduced amount. If you are driving a turbo "adjusted" for street driving, it is no longer a 500 hp car. Come on. And I STILL think driving a 500 hp car on the street is stupid. By driving 500 hp, I mean USING 500 hp. Same thing. This does not go to say if you can control it, if it can be fun, its not worth it, etc... just that I think it is stupid.

Guest 240hybrid Posted February 7, 2003 Share Posted February 7, 2003 I dont think that a 500HP Z is stupid....kinda a nice thought to have that much power in such a light car, Dangerous too. Though smoking a ferrari at a red light that some yuppie bought in an effort to be the fastest on the street is great You'll have his jaw dropping when he sees the classic/antique verhicle plates when hes eating your dust. 500HP is not needed as mentioned but something to keep you at peace knowing that you have all that power when its needed.

BLKMGK Posted February 28, 2003 Share Posted February 28, 2003 Hrm, I drive a 500RWHP car daily, nothing at all wrong with that. Okay, I'll admit I park it when it snows and the streets aren't cleared but otherwise I do indeed drive it everyday It's also a bit heavier than a Z so it is indeed slower than a Z would be. That said - the car only makes 500+RWHP with my foot WOT and tached out. Most of the time I'm not in boost. Would I drive a 500RWHP N/A car? No way, it would be a gas pig and probably not very pleasant. A turbo car is much more docile than a N/A that needs all sorts of work to make that power. So, what's it like? Don't go WOT in the first three gears and be DAMNED sure the pavement is smooth, flat, and free of sandsaltcrap in 4th. I have ZERO doubt this car could get away from me if I wasn't careful. Right around 3700RPM power SHOOTS up and continues climbing until you let off the gas - it's linear past 4KRPM. That makes it a little easier to drive once things are spooled. Tires on this puppy are Nitto 555 in a 275 series. Come warmer weather it WILL get 555R DRs as there's no fun in spinning the tires and IMO it'll be safer. 550RWHP is what the car dynoed at and that was on a Mustang dyno with boost lower than I'd like to have run and they ended the run 1K RPM before redline with power still rising. With tuning and more boost I expect to make more power for sure but probably will have to run race gas or Methanol injection to do it. On the street that's probably excessive but if I can hook it I will cook it and simply lower the boost a bit for daily driving. I should be in the mid 11s pretty easily right now, in a Z this would be 10s IMO. I DO know of some Supra owners that can run 10s on a daily driver but you have to admit that's pretty sick in a street car with A/C. I'd agree with building a little less power, driving it, breaking it, and then maybe turning it up some. Turbos are great for tunrning the power down and then switching to STUN when needed Ask Scottie what it's like to drive HIS car. Make no mistake - he can burn the tires at will and he has to be careful - I've seen him do it. The lighter Z chassis makes 500HP a pretty sick fast proposition Quote Link to comment Share on other sites More sharing options...
Scottie-GNZ Posted February 28, 2003 Share Posted February 28, 2003 I think the problem here is that a lot folks in this thread do not understand the forces involved here, so I am going to attempt to use the numbers from my most recent run at Reynolds to put it in perspective. We all accept any car that can do 0-60 in under 6-secs as being pretty quick. Most recently Chrysler unvieled the Tomohawk, a Viper V-10 powered motorcycle. They claimed 0-60 in 2.5-secs and I am willing to bet many in this thread would sh*t their pants if they mounted that thing and twisted the throttle. At Reynolds my car had a 60' of 1.49 and 6.621 @ 104.34 at the 1/8-mile. I plotted an acceleration curve from my datalogger and this is what it amounts to: 0-60 in 2.16-secs and 0-100 in 6.21-secs! Yes, it blows the Tomohawk away so you better believe this should scare you as much as riding that bike. Any Z-car with 500hp has that capability. More times than I like to recall I have left a stripe in my shorts launching my car and worse, almost losing it on the the top-end. That is with racing tires, IMHO a well setup suspension, on an enclosed racing circuit and with a healthy dose of respect for this beast. With that kind of power there is no margin for error. We all love our Z cars but in stock form the chassis, brakes and suspension is really crap compared to new cars like the Supras and we want to add 500hp in that short wheelbase on the street with street tires? There is no way in hell I would do on the street what I do with my car on the strip. On the other hand, I use to street race when I was younger and I can tell if I had this kind of power back then I would be posting from Heaven.

Guest empracing Posted March 1, 2003 Share Posted March 1, 2003 if I had this kind of power back then I would be posting from Heaven. You mean your not in heaven now? thats seirously quick to the 100kph/60mph i used to get scared at 2 secs to the 60mph too scottie now i just wish i could do it again haha i can emagine a 500hp car that is spinning 60% of that power but not one thats putting it to the pavement on the road thats mayhem!!
